It wasn't until I was 26 or 25 when I started sending work out to magazines.

I used to think...that I had to be careful with how much I lived. As if life was a pocketful of coins. You only got so much and you didn't want to spend it all in one place...But now I know that life is the one thing in the world that never runs out. I might run out of mine, and you might run out of yours, but the world will never run out of life. And we're all very lucky to be part of something like that.

I've been getting into Nick Drake lately, the folk singer. Sad, gorgeous stuff.

Time is a slippery thing: lose hold of it once, and its string might sail out of your hands forever.

I write reviews of science books for the Boston Globe, so I like to give science books.

I guess whatever maturity is there may be there because I've been keeping a journal forever. In high school my friends would make fun of me - you're doing your man diary again. So I was always trying to translate experience into words.

It took me about three years to write About Grace. I wasn't teaching two of those years, so I was working eight-hour days, five days a week. And it would include research and reading - it wasn't just a blank page, laying down words.
